The document discusses CRT (cathode ray tube) monitors. It explains that CRT monitors operate similarly to televisions by using an electronic cathode ray tube screen linked to phosphorescent material that glows when struck by electrons. Some advantages of CRT monitors are that they can operate at any resolution without needing to recalibrate images, support high pixel resolutions, and have fast response times. However, disadvantages are that they produce moire patterns, can have geometric distortions, are large and bulky. In conclusion, CRT monitors were commonly used but support multiple resolutions without losing image quality, though they are bulky.

CHARACTERISTICS OF CRT

3. The most commonly used output device is a monitor.
Different types of monitors have different technologies
used in them but the operations of commonly used
monitors is based on the CRT.

4. A monitor operates very similarly to how your regular
television set works. The principle is based upon the use
of an electronic screen called a cathode ray tube. Which is
major part of monitor. The CRT is linked with a
phosphorous material that glows when it is struck by a
stream of electrons.

5. They operate at any resolution ratio without the need
for recalling the image.
CRT runs at the highest pixel resolutions generally
available.
CRT have fast response times and no motion artifacts.
CRT are less expensive than comparable displays using
other display technologies.
CRT produces the very best color and gray-scale and are
the reference standard for all professional calibrations.

6. All color CRT produces annoying moiré patterns.
Subject to geometric distortion and screen regulation
problems.
Some CRT have a rounded spherical shape screen.
They are large, heavy and bulky.

7. A CRT monitor can support many output resolutions
without losing quality of the image.
CRT monitor is bulk its cheap now a days.
